I got one bios here, it is a original Sapphire bios already modded with 1.33Voltage on the core normally but none of the clock speeds where changed.

If somebody would be so kind to modify this bios to 800/1000 with 1.33 voltage on core and some 5-10% more voltage on memory then stock.

Also a qeustion was, can you edit the fan speeds ? The i would have the fan fixed on 60% in 2D and 3D.

Another thing is, i don't know if this bios is modified to pass the 777 lock on the 3850's, so look after that if you can .

So in short:

3D = Core @ 800Mhz / Fan @ 60% / Voltage @ 1.33V
3D = Mem @ 1000Mhz / Fan @ 60% / Voltage @ 2.0V

2D = Core @ 600Mhz / Fan @ 45% / Voltage @ 1.22V
2D = Mem @ 800Mhz / Fan @ 45% / Voltage @ 1.8V

Checksum corrected and 777 lock gone ?

If somebody can make this for me i'm VERY happy !!

I dont think mem voltage can be modified in BIOS, also Im not sure where you code the fan speed either. Also...getting a completly unlocked BIOS would require you finding the v71 for your card type.
If there is indeed a 77x mhz lock on these cores thats interesting cuz my core goes to 770...anything above it locks in 3d. Im using the v71...
cuz AFAIK there is only a 860mhz lock in bios's for 38xx cards....
anyone have more on this ?
